Building a low cost, highly scalable, enterprise level computer forensics lab Raoul “Nobody” Chiesa, Ethical Hacker came to security. When the server number grew we had Foreword trouble finding data around the local network. Building a SAN gave us only new headaches: we Desktop hard drives are becoming bigger and bigger. needed new expensive hardware for the infrastructure However, server hard disks are not growing up at the same rate. (Fiber Channel controller and switch), and both disks and storage units were much more expensive. At present, you can buy a 1.5 Tb Sata hard drive for Otherwise we still needed some way to share the SAN about 150 €. file system to the analysis machines. A common 146 Gb 2.5 SAS hard drive costs about 250 We looked for something new in the market. We found €. The Cost to Megabyte ratio means SAS technology is many cluster file system like ocfs 15 times more expensive. (/projects/ocfs2/), lustre This is a problem. Desktops are getting bigger but you (/index.php?title=Main_Page) and need even bigger storage to store all data related to an others, but they were too tied to cluster logic. investigation and it must be kept also online and secure. We found some interesting network file systems like Currently, bigger hard drives are affordable but very
